PATENTEB MAYZU I975 SHEET 3 BF 3 FIGS PROTECTIVE SEAT COVER OF THIN PLASTICS FILM OR SHEET, A PACKAGE FOR THE PROTECTIVE SEAT COVER AND LIKE THIN PLASTICS ARTICLES, AND A PROCESS OF MAKING THE PACKAGE This invention relates to a protective seat cover of thin plastics film or sheet which is of at least substantially rectangular outer configuration and at two opposite ends has pockets extending over the whole of the width of the film or sheet, one of said pockets being intended for cooperation with the back rest of the seat of an automobile while the other pocket is for cooperation with the front part of the seat remote from the back rest. Characteristic of this protective seat cover is that at the ends having the pockets the cover is provided with bellows which are folded into said pockets. By the provision of these bellows the protective seat cover which is primarily to serve as an automobile seat cover in conjunction with repair jobs, can be used with seats of varying sizes. It can also be used with seats having head rests, and a particularly favourable junction with the form of the head rest is obtained when the bellows which, like the pockets, extend over the whole of the width of the protective seat cover are united with the pockets at the longitudinal edges thereof.

The invention also relates to a package containing a large number of protective seat covers or similar at least substantially rectangular articles of thin plastics or like material.

Characteristic of this package is that it is a rectangular container preferably of cardboard, corrugated board or like material and containing a number of bundles of the thin plastics article, that each bundle is doubled about a plate, that the doubled bundles are placed in juxtaposition with the folds turned upwardly in the container, and that plates are interleaved with the doubled bundles.

The invention thus provides a package for thin plastics articles, from which package the articles can be withdrawn one at a time without being damaged since the plates interleaved with the doubled bundles will considerably reduce the frictional resistance at the withdrawal of the articles from the container.

Finally, the invention also relates to a process of making the package. This process is characterized by placing the container with one of its sides on a base and with the opposite side swung away from the container, doubling bundles of the article in turn of order about plates and putting them on top of each other on the container side bearing against the base with the folds facing the upper end of the container and with the opposite edges engaging the container bottom, interleaving a plate with each doubled bundle, moving the side swung away from the base into position opposite the side bearing against the base and securing it in said position.

The invention will be more fully described hereinbelow with reference to the accompanying drawings which illustrate the protective seat cover and the manufacture of an embodiment of the package chosen by way of example. In the drawings:

FIG. 1 is a plan view and side view of a bundle of protective seat covers;

FIG. 2 is a side view and plan view of a bundle doubled about a plate;

FIG. 3 is a developed plan view of the container blank;

FIG. 4 is a view of the partly erected container blank with a doubled bundle placed therein;

FIG. 5 is a front view of the finished package;

FIG. 6 is a cross section thereof;

FIG. 7 is a perspective view of the package in the opened state.

The articles 1 which are to be accommodated in the package are essentially rectangular units of thin plastics or like material, such as protective seat covers of thin plastics film or sheet. The seat covers at both ends have pockets 2 and 3. The pocket 2 is for cooperation with the back rest of the seat of an automobile while the pocket 3 is for cooperation with the front portion of the seat facing away from the back rest.

According to the invention, the protective seat cover 1 is provided at the ends having the pockets 2, 3 with bellows 4 and 5 which are folded inwardly into the pockets 2 and 3. Like the pockets 2 and 3 these bellows 4 and 5 extend over the whole of the width of the seat cover 1, and the bellows 4 and 5 are united with the pockets 2 and 3 along the longitudinal edges thereof.

The seat cover 1 is preferably prepared from a tubing of thin plastics. The tubing is flattened and doubled at the edges, the doubled portions constituting the bellows 4 and 5. A longitudinal strip corresponding to the distance between the pockets 2 and 3 is cut out of the tubing. By cutting and welding operations transversely of the tubing the seat cover 1 is thus formed in a simple and rational manner.

The rectangular articles 1. of thin plastics are arranged at their manufacture in bundles 6 of say articles. These bundles 6 are doubled about plates 7 which are essentially half the size of an article 1. The bundles 6 thus doubled are placed in juxtaposition with the folds 8 facing upwardly in a rectangular container 9, plates 10 being interleaved with the doubled bundles 6. The plates 7 and 10 are preferably of equal size and of equal nature, it being essential that at least the plates 10 have a low frictional resistance to the plastics articles. The plates 7 and 10 therefore preferably consist of cardboard, corrugated board or like material which is preferably smoothed.

The container, preferably of the same material as the plates 7 and 10, is made from an integral blank which is shown in developed plan view in FIG. 3. This blank is divided by crease lines into panels 11 to 15, wherein the panel 11 is the front of the container, the panel 12 the bottom thereof, the panel 13 the rear thereof, the panel 14 the upper side of the container, and the panel 15 a closure flap cooperating with the front 11 of the container. Laterally of the panels 11 to 15 the blank is provided with flaps which in conventional manner constitute the end portions of the container 9.

At the manufacture of the package the container 9 is placed with its rear side 13 on the base and with the front side 11 swung away from the container 9 proper, as will appear from FIG. 4. The bottom 12 and the end walls 16 and 17 have thus been erected. In the container 9 thus formed the bundles 6 which have been doubled about the plates 7 are placed on top of each other in the container bearing against the base with the folds 8 facing the upper end of the container and with the opposite edges engaging the bottom 12 of the container. A plate 10 is interleaved with each doubled bundle 6, and the doubled bundles 6 and the loose plates are alternately placed on top of each other in the container. When the container has been filled in this manner with bundles 6 and plates 10 the container front 11 is moved into position opposite the rear side 13 and is secured in this position with the aid of the flaps l8 and 19. Finally, the container 9 is closed in that the closure flap 15, for instance with the aid of staples, is united with the front side 11, as will appear from FIGS. 5 and 6. Before closure is performed the flaps 20 and 21 are folded down against the upper ends of the doubled bundles 6. The flaps 20 and 21 then serve as supports for the panels 14 and in the opened condition of the container 9, as will appear from FIG. 7. In this position, one article 1 at a time can thus be withdrawn from the container 9 without being damaged although the container 9 initially is well filled with articles.

The articles 1 in the container 9 shall fill out the container 9 completely. The rectangular container 9 therefore is of substantially the same height as the doubled bundles 6. To reduce the frictional resistance to the withdrawal of the articles 1 from the container 9 at least one of the two container sides 11 and 13 against which the doubled bundles 6 bear with their sides, is lower than the container 9. Thus, according to the embodiment illustrated, the front 11 is lower than the container 9 proper. By extending the slits 22 and 23 between the panels 14 and 15, on one hand, and the flaps and 21 on the other hand, the side 13 could also be made lower than the container 9 in the opened condition thereof.

As will have appeared from the foregoing, the panels 14 and 15 form the container cover which in the closed position is adapted to extend at least down to the upper edge of the low front 11.

The container 9 illustrated in the drawing is primarily intended for accommodation of four doubled bundles 6 of one hundred seat covers in each bundle. For the sake of clarity, however, only three bundles 6 have been shown in FIG. 6. The seat cover 1 has a length of 115 cm and a width of 78 cm. The pocket 2 is 60 cm deep whereas the pocket 3 is only 16 cm deep. The bellows 4 and 5 are 10 cm deep. The container blank is 162 cm long and 116 cm wide. The panels 11 to 15 have a width of 80 cm, while the flaps 16 to 21 have a width of 18 cm. The front 11 is 45 cm high, while the rear side 13 has a height of 60 cm. The width of the bottom 12 and the upper side 14 is 18 cm, while the closure flap is 21 cm long. The latter thus overlaps the front 11 by 6 cm in the closed position.

The plate 7 in the doubled bundles 6 and the plates 10 interleaved with the doubled bundles 6 have a length and a height slightly smaller than that of the container 9. According to the above example, the plates 7 and 10 have a length of cm and a height of 57 cm.

Of course, the size of the container can be varied within broad limits but it must, of course, conform to the thickness of the thin plastics articles to be packed therein.
